Air Cleaner Base
An automotive air cleaner base is a component that is part of the air intake system in a vehicle's engine. The air cleaner base functions by providing a stable and secure mounting point for the air cleaner element and ensuring a proper seal between the air cleaner and the carburetor or throttle body. The air cleaner base is typically made of metal or plastic and is designed to accommodate the shape and size of the air cleaner element. The air cleaner base also features an inlet that connects to the air intake duct or air filter housing, which allows air to flow into the air cleaner element. The air cleaner base also features a mounting flange that is bolted to the carburetor or throttle body and secures the air cleaner in place. A malfunctioning air cleaner base can cause a range of problems, including poor engine performance, reduced fuel economy, and increased emissions. Therefore, it is important to inspect and maintain the air cleaner base regularly to ensure it is functioning properly and providing a proper seal for the air cleaner element.

When choosing a flat or dropped base air cleaner, first confirm the carburetor or throttle body mounting flange diameter. Next, determine the outside diameter that will fit under the hood. In addition, measure if a drop base air cleaner is needed to gain more hood clearance. Finally, from the remaining compatible options, choose the air cleaner base that best fits your needs as well as your budget.
